Heidi F. Diedrich, Director, Integrated Communications

Heidi DiedrichHeidi Diedrich brings to Sherwood Communications nearly 20 years of integrated communications experience at the international, national, and grassroots levels. She is recognized by for her ability to apply strong analytical and critical thinking to strategic communications programs that align with and advance an organization’s business objectives and marketing goals.

This experience complements her work with Northwestern University’s Kellogg School of Management, where as director of media relations she established the school’s first in-house international media relations program. Under her direction, the program generated impressive media results within its first year, including coverage in The Economist, Financial Times, Businessweek, The Wall Street Journal and The Washington Post, as well as National Public Radio.

While with National Dairy Council (NDC), Diedrich was responsible for establishing the first national strategic integrated communications plan for a $250-million campaign to reduce childhood obesity in the United States. The initiative, developed in partnership with the NFL, reached 60,000 U.S. schools and 36 million youth in its first year. Efforts led to the program being accepted under First Lady Michelle Obama’s “Let’s Move” campaign in 2010.

Previously, Diedrich led NDC’s national and regional media relations programs. In this role, she established an integrated media relations plan to promote and protect U.S. dairy products through leveraging scientific research and educating public policy leaders and third-party experts. Efforts included traditional and digital communication, as well as a national news bureau and panel of independent nutrition experts who endorsed dairy in the human diet, based on published nutrition research.

Diedrich also led public affairs for a major regional health care trade and advocacy association in Chicago, providing leadership and vision to realign the association’s public affairs initiatives to better reflect and support member institution needs. Under her direction, the association’s marketing and communications collateral were rebranded, the department was restructured, and communications activities were streamlined to secure the association as a leading regional expert on a range of health care issues, including disaster preparedness and response, patient safety, care for the uninsured, and health care workforce shortages.

While with Loyola University Health System, Diedrich held positions of increased responsibility, rising through the ranks to eventually lead the academic medical center’s media services division. Under her direction, international and national media coverage of the center’s bench and clinical research achievements increased nearly 200 percent in one year. She also counseled senior executives and physician leaders on internal and external communications initiatives.

She began her public relations career at a small boutique firm outside Chicago, collaborating with a small team of colleagues to create the first consumer public relations program for Whirlpool Corporation, launching the global company’s first environmentally friendly refrigerator at a time when the sustainability movement was in its infancy.

Before joining the public relations profession, Heidi worked as photojournalist for a small suburban newspaper chain near Chicago and as a stringer for the Associated Press and United Press International. She lives in Chicago.
